An unsold TV pilot from 1963 called "The Plot Thickens". Same concept as the early 1950s series "Crawford Mystery Theatre" (of which only a single kinescope survives...anyone able to upload it?). In this pilot, a panel is shown a short film about a crime, and then has to guess who the guilty person is. Features Groucho Marx as one of the panel members. Could someone please check that this is public domain?

Well, this could've been a fun little show. I agreed with another reviewer up to a point. Groucho DID ruin the game but I didn't enjoy his cheap, sleazy brand of "humor". Stupid, slimy sex jokes from a leering grandpa salivating over attractive women creeped me out and it destroyed what had the potential to be an interesting game. And, from the words of the announcer at the end, the producers intended 'Gross-o' to be a weekly panelist so this was doomed from the start. Too bad.

It may interest people to know that this was done as a series on British ITV.It was called Whodunit and was hosted by the late Jon Pertwee of Doctor Who fame.It was broadcast in the late 70's to early 80's and unfortunatly is'nt public domain

I'm currently on an unaired-pilot kick (and the Archive has no shortage of them), but this is the first one I really feel could have been something. The scenario is very clever, and the production values are quite good for the time period.

Bringing on Groucho Marx was a delightful mistake, because he unrepentantly attempts to screw with everyone (my personal favorite was him pestering the host about whether the prop prize bags actually contain money, something the host is very cagey about). He's clearly exasperating to the other players, the hosts and the story members, and I love it.

All in all, it's a shame this never saw the light of day, but it's a very entertaining half hour.

I can see why this never went into production against The Twilight Zone,Combat,and Perry Mason,it was a bit dated and looked "50's-ish".Anyway,the real gem here is Groucho,what an unexpected pleasant surprise,and really adult comedy considering the sqeaky clean era of tv at that time.
